Overview About RIPE and RIPE NCC IPv4 address pool exhaustion IPv4 depletion process IPv6 deployment IPv6 in Saudi Arabia How to request IPv6 IPv6 Act Now

The five RIRs
IPv4 Depletion

IANA and RIRs IPv4 pool
Data Projection
Today

IPv4 exhaustion phases
time
IANA pool exhausted
IPv4 still available. RIPE NCC continues
distributing it
Each of the 5 RIRs
given a /8
RIPE NCC reaches final /8
policy from last /8 applies
RIPE NCC pool
exhausted
RIPE NCC can only distribute IPv6
now
?

IPv4 Run Out Fairly
Gradually reduced allocation / assignment periods
- 12 months (January 2010) - 9 months (July 2010) - 6 months (January 2011) - 3 months (July 2011)
50% has to be used up by half-period
8
Last /8
We do things differently! Ensures IPv4 access for all members
- 16 000 x /22 in a /8 - members can get one /22 (=1024 addresses) - must already hold IPv6 - must qualify for allocation
/16 set aside for unforeseen situations - if unused, will be distributed
No PI so far. May change.

Our slice of IPv4

Legacy Space
IPv4 addresses distributed prior to the RIR system Why register?
- Benefits: - legitimize holdership
- update reverse DNS delegation
- use membership services
- no fees! - Risks:
- frozen data in the RIPE Registry
- vulnerable to hijackers

Additional IPv4 allocation requirements
80% must be in use Tidy up current records Request a list of invalid assignments Send an IPv4 Additional Allocation request We will audit you
12
Transfer of IPv4 allocations
Transfer unused allocations to another LIR Minimum allocation size /21 Evaluated by the RIPE NCC
IPv6 Deployment
14
IPv6 Distribution
15
IPv6 in Saudi Arabia
Only 36% of LIRs have an IPv6 allocation
16
Getting an IPv6 allocation
Requirements: - Be an LIR - Plan to make assignments within two years
Minimum allocation size /32 Announcement as a single prefix recommended
17
Getting IPv6 PI space
Requirements: - Meet the contractual requirements
Minimum assignment size /48
18
IPv6 Allocations and Announcements
Extension of the minimum allocation size
Awaiting decision Initial IPv6 allocation from /32 to /29 Enables small LIRs to deploy 6RD
